JAJSN61F May 2015 – March 2022 TUSB320
PRODUCTION DATA
Active mode is defined as the port being attached. In active mode, all GPIOs are operational, and I2C is read / write (R/W). When in active mode, the TUSB320 device communicates to the AP that the USB port is attached. This happens through the ID pin if TUSB320 is configured as a DFP or DRP connect as source. If TUSB320 is configured as an UFP or a DRP connected as a sink, the OUT1/OUT2 and INT_N/OUT3 pins are used. The TUSB320 device exits active mode under the following conditions:
During active mode, I2C cannot be used to change the mode configuration. This can only be done if TUSB320 is in an unattached state.
